“Strummer Newcomb Cook, born October 20, 2017. Thanks and ever thanks to the extraordinary Doctors, Nurses and staff at Mount Sinai for helping bring this utter joy into our lives,” Stiles Instagrammed to the world. “Hello, World!”

Stiles, 36, and Cook, recently tied the knot on a beach in Seattle over Labor Day weekend.

Stiles and Cook have been engaged since Christmas of 2015. The two had first met on the set of the film Go With Me released back in 2015 where cook was working as a camera assistant. Sounds like there will be plenty of great home videos in the future for this happy couple.
